Sheet "Regression Analysis" | Quiz 3 (chapter 8-9) + Simple Linear Regression |
The results of quiz 3 are disappointing! I'd like to dicuss the reasons for this in class so please have a look at the quiz and the solutions. I "curved" the result, taking away two points from the maximum because in question 3 (22%) and question 7 (43%) most of you gave a wrong answer - why? (The points achieved in these question still count anyway) --> Quiz 3 + solutions + results + overview |
